// Format meanings:
//
//		[%a]   The abbreviated weekday name (۳ش)
//		[%A]   The full weekday name (یکشنبه)
//		[%b]   The month name (اردیبهشت)
//		[%B]   The month name in pinglish (Ordibehesht)
//		[%d]   Day of the month (01..31)
//		[%e]   Day of the month (1..31)
//		[%j]   Day of the year (1..366)
//		[%m]   Month of the year, zero-padded (01..12)
//		[%_m]  Month of the year, blank-padded ( 1..12)
//		[%-m]  Month of the year, no-padded (1..12)
//		[%w]   Day of the week (Sunday is 0, 0..6)
//		[%x]   Preferred representation for the date alone, no time in format YY/M/D
//		[%y]   Year without a century (00..99)
//		[%Y]   Year with century
//		[%H]   Hour of the day, 24-hour clock (00..23)
//		[%I]   Hour of the day, 12-hour clock (01..12)
//		[%M]   Minute of the hour (00..59)
//		[%p]   Meridian indicator ("بعد از ظهر" or "قبل از ظهر")
//		[%S]   Second of the minute (00..60)
//		[%x]   1392/04/02
//		[%-x]  92/4/2
//		[%X]   Preferred representation for the time alone, no date
//		[%Z]   Time zone name
//		[%%]   Literal %'' character
//
// Example:
// 		jalali.Strftime("Printed on %Y/%m/%d", time.Now())   #=> "Printed on 1392/04/02"
